BEER-DRAWING APPARATUS.

Specification .of Letters Patent.

Patented Apr. 27, 1915.

Application filed May 15, 1914. Serial No. 838,661.

To all whom it may concern Be it known that I,--.CHRISTIAN SAHLEN- DER, of New York, borough of Brooklyn, in the State of New York, have invented certain new and useful Improvementsin Beer- Drawing Apparatus, of which the following is a specification.

This invention relates to an improved apparatus for drawing beer by means-of a stationary tank located in the basement of the place of sale, and by means of a delivery tank-wagon, so that the liquid is delivered in bulk, and the use of the well-known shipping-kegs and beer-raising devices is dispensed with.

For this purpose the invention comprises a beer-tank, a free piston therein, a collapsible piston-rod adapted to bear on the piston, a spring in the piston-rod, and means for compressing the spring and telescoping of the piston-rod, so that the beer at the other side of the piston is placed under the pressure of the expanding piston-rod.

In the accompanying drawings, Figure 1 represents a side-elevation of my improved apparatus for drawing beer, showing it connected with a delivery tank-wagon for filling the same. Fig. 2 is a vertical central section through an apparatus embodying the invention, showing the same in its uncharged condition, Fig. 3 shows the apparatus with the spring compressed, but piston not raised, Fig. 4 shows the piston-rod raised, the spring being compressed, Fig. 5 shows the apparatus charged and in operating condition, Fig. 6 is a plan-view of a key adapted to be used for locking the parts when the spring is compressed. Fig. 7 is a cross-section of the key shown in Fig. 6; and Fig. 8 is a view of the lower pipe system of the tanks in a plane at right angles to the views shown in Figs. 2, 3, 4 and 5.

Similar characters of reference indicate corresponding .parts throughout the several figures of the drawing.

In my improved beer-drawing apparatus, the use of shipping-kegs into which the fermented liquids are racked oil' and in which they are delivered to the customer is entirely dispensed with, and in place of the same one or more stationary beer-drawing apparatus used, in the basement of the saloon or other place for dispensing liquids. Each apparatus comprises a tank 10 which is preferably cylindrical in form, and may tubular screw 19, which passes centrally through the head 16. Said screw 19 is attached at its lower end to the upper section 12 of the piston-rod. A strain-rod 20 is secured at its lower' end to the lower end of the piston-rod section 13, and is made of such length as to project above the end of the screw 19 when the piston-rod is collapsed. Within the piston-rod is a helical compression-spring 21 which is compressed when the piston-rod is collapsed. One end of said spring abuts against the lower end of the lower piston-rod section, and the other end abuts against the lower end of the screw 19 at the top of the upper pistonrod section. A supply-pipe 22, controlled by valve 23, is connected with the lower head 24 of the beer-tank by means of a central pipe 50 herein. A discharge-pipe 25, controlled by a valve 26, is also connected with said head by means of the said central pipe 50 andextends therefrom upwardly to the refrigerating coil 30 and faucet 31 at the bar. To the upper end of the lower pistonrod section 13 is connected an angular gage-rod 27, which extends upwardly and is guided in the head 16, and then beyond the same extends through the floor into convenient view of the bartender for indicating at all times the quantity of beer contained in the tank.

The apparatus being in the relaxed and empty condition shown in Fig. 2 and it being desired to place the same in operation, the first step is to compress the spring which isto afford the means of power for subse quently discharging the beer at the bar. For this purpose the hand-wheel 18 is' rotated so as to work the screw 19 downwardly, thereby moving the piston-rod section 12 downwardly within the lower section 13 and compressing the spring, until finally the position of the parts is as shown in Fig.

3. The upper end of the rod 20 is at this time dxposed above the screw 19, as'indicated in F ig. 3. At said exposed portion it isprovided with two notches, one on each side, whereby the rod is adapted to receive a key 28, as shown in Fig. 6. The key having been placed upon the rod, the hand-wheel is now turned in the reverse direction, thereby raising the screw, and with it the rod 20 and the collapsed piston-rod, so that the parts assume the position in Fig. 4, in which the lower end of the piston-rod is at the extreme upper .end of the tank, while the piston remains lying on the bottom. Beer I under pressure 1s now turned on through the pipe 22 and valve 23, the same enters the tank below the piston and raises the piston, and fills the tank. The piston finally comes to rest against the lower end of the pistonrod at the top of thetank, and the beer in the tank is under the pressure under which it was forced into the tank. The tank having been thus filled and the supply shut ofl", connection is now made with the bar through the discharge-pipe 25 and valve 26. The key 28 is removed, and thereby the full force of the spring 21 is allowed toexert itself in expanding the pistdn-rod and forcing the lower end of the same against the piston 11 and the beer in the tank below the same, whereby the beer is forced through the discharge-pipe to the bar with the proper pressure for delivery. The beer is thus drawn off at intervals as occasion demands, until finally all the beer is withdrawn from the tank, and the parts will then be found in the position of Fig. 2, when the operation of filling the tank, as before described, may be repeated.

. The rise and fall of the lower section of the piston-rod 13 causes the corresponding rise and fall of the gage-rod 27, the 'position of which, before the bartender, on the floor above, indicates to him the gradual descent of the piston and the corresponding decrease in the quantity of beer from time to time 4 within the tank. Any desired number of tanks may be employed, threebeing shown in Fig. l, and the same may be filled and discharged successively or simultaneously.

The beer or other fermented liquid is delivered to the tank or tanks 10 by a su plywagon which consists of a wheeled rame and a tank 29 supported on said frame. The tank is provided with a dome 32 which is connected with the receiver 33 for carbonic acid gas that is supported below the tank of the frame of the wagon, said .re-

ceive'r being provided with a pressure-reducing valve 41 which is connected by a pipe 34 with the dome 32, as shown in Fig. 1. Thetank is provided at its bottom-part with a discharge-pipe 35, having a sto -cock' 36, which discharge-pipe isconnecte by a coupling and flexible hose 37 with acoupling 38 of the stand-pipe 39. The carbonic acid gas receiver 33 is also connected with the discharge-pipe of the tank by means of a held under pressure of carbonic acid gas,

no-fuming of the same takes place during its delivery from the tank or wagon to the tanks at the place of sale. When the tankwagon arrives at the place of use, the hoseconnection with the stand-pipe 39 is made.

The attendant then goes in the basement and closes the valve 26 at one of the tanks 10, and opens the valve,23. He then returns to the tank-wagon, opens the discharge-cock 33 of the same and the cock 43 of the standpipe. The liquid is then transferred under pressure of carbonic acid gas, without fuming, into the tank, so as to lift the piston 11 1n the tank, the piston-rod 13 having been lifted as before described. The pressure of the liquid entering the tank lifts the piston until the same arrives at the upper end of the tank. The topof the'tank is provided with a vent45, so as to allow the piston to rise and to allow atmospheric ressure to act on the top of the iston durlng the discharge of the tank. 'Vben the tank is nearly filled with liquid, the discharge-pipe is closed and the regulating valve of the carbonic acid supply-pipe opened, so that by the pressure of the carbomc acid all the liqtransferred into the tank and thereby the uid in .the stand-pipe and supply-pipe 1s pistonlifted to its full extent and at the same time all the liquid in the supp and stand-pi with carbomc acid gas. The cock of the stand-pipe is then closed, and the hose-connection uncoupled and replaced upon the tank-wagon. he presence of carbonic acid gas in the supply-pipe prevents the air from entering into the same, and keeps the same from entering into the beer. The sto -cock of the gas supply-pipe, is closed ofl" efore the hose is disconnected from'the stand-pipe.

The advantages of my improved apparatus for ,.drawing beer and other fermented liquids are that the use of wooden shippin -kegs by which the beer is shipped from the rewery tothe consumer or to the place of sale are dispensed with. Second, that the inconveniences of tapping the kegs and connecting them with the discharge-faucet at thejbar are removed. Third, that the washing and pitching of the kegs and the racking ofl' of-the liquid into the shipping-kegs from the storage-casks are likewise dispensed with, c ,h a, ens der ble sav results both .yr pe removed and the same filledto the brewer and customer, for the reason that the liquid is sent out in bulk in the delivery tank-wagon, and the handling of the large shipping kegs and return of th em ty kegs is dispensed with.

ne embodiment of the invention has been described, but it is obvious that changes may be made therein without departing from the spirit of the invention as set forth in the appended claims.

I claim: 1 1. A beer-drawing a paratus, comprising a cylindrical tank, a ree piston therein, a collapsible piston-rod adapted to bear upon said piston, a spring normally expanding said piston-rod, means for collapsing the piston-rod before the charging of beer into the tank, and valved supply and discharge pipes connected with said tank at the sidev of the piston opposite the piston-rod.
